Background & Biography
Jun Hasegawa built his early career around technology businesses in Japan before establishing Omise. The company’s 2017 OmiseGO crowdfunding document describes experience in e-commerce, mobile payments and product design, including management positions at Alpha-do. Those are contemporaneous company biographical claims, rather than a complete independently reconstructed employment history. They establish a business and product-development background without suggesting that Hasegawa personally authored the later blockchain protocols associated with his companies.
Omise began in 2013, with Ezra Don Harinsut as a fellow co-founder. Its payment service launched in Thailand in 2015 before expanding into other Asian markets. The practical offering centered on helping merchants accept online payments and manage the connections to payment processors and acquirers. Thailand remains a central operating market in this profile, while the group’s Japanese corporate connections and other international operations are also material to its history.
The organization’s changing names can obscure that continuity. Reuters reported an $80 million Series C financing in June 2020 under the SYNQA name, identifying Hasegawa as founder and CEO. In May 2022, the company announced that SYNQA would become Opn, alongside a further financing announcement. In March 2025, its own release confirmed a return to the Omise brand. These are stages in the development of a payments group, not evidence that every historical subsidiary retained the same ownership or operational relationship throughout.
Current leadership evidence is clearer than many older conference biographies. Omise’s live company page lists Hasegawa as founder, group CEO and representative director, while separately identifying its chairman, finance chief, operating chief and technology chief. In May 2025, Omise announced Harinsut’s departure after his service as co-founder, board director and former president. Recognizing that transition preserves the contribution of the original partnership without presenting its early executive structure as unchanged.
Notable Contributions
Omise’s payment infrastructure is the longest-running part of Hasegawa’s public record. Its current business covers merchant checkout and transaction management, with additional offerings for platforms, banks and enterprise development. The contribution is organizational as well as technical: merchants need a service that connects their software to the payment methods their customers use. Hasegawa’s executive role places him within the business’s strategic development, while engineering, operations and partner integration remain team responsibilities.
OmiseGO extended that work into public-blockchain infrastructure. The June 2017 crowdfunding document identified Hasegawa as founder and CEO of both Omise and OmiseGO and described a separate technical, business and product team. Its plans concerned decentralized value exchange and payment-related infrastructure. The document is valuable evidence of the original ambition and leadership, but proposed network capabilities and token arrangements should not be treated as proof that each element was delivered as written.
A later operational milestone arrived in 2020. Bangkok Post reported that OMG Network, then SYNQA’s blockchain arm, had launched its mainnet platform in June, with Vansa Chatikavanij representing the network’s management. In December, Cointelegraph reported its acquisition by Genesis Block Ventures. These developments explain why Hasegawa’s historical founder connection should be separated from a current OMG executive appointment. They also prevent Omise’s subsequent payment activity from being presented as if it automatically operated on the OMG token or network.
The acquisition of MerchantE broadened the payment group’s reach in a different direction. In November 2022, Opn announced that it had acquired the US payment-processing business, whose capabilities included the backend services needed to support merchant transactions. The announcement said MerchantE would retain its brand and Georgia headquarters, while the parent remained headquartered in Tokyo. It documented a completed acquisition, with technology sharing and jointly developed offerings described as future integration opportunities rather than already achieved results.
The 2025 return to the Omise name came with an explicit focus on AI-assisted payment tools. The March announcement outlined planned capabilities for developer assistance, routing and analytics. A more specific release followed in November, when the company announced Omise MCP, connecting AI agents with its payment tools through the Model Context Protocol. This chronology matters because the earlier product direction and the later announced release represent different stages of execution.
Omise described the MCP release as supporting tasks including payments, refunds, subscriptions and transaction management. Hasegawa presented it as a shift toward systems that can act within payment workflows, while technology chief Amborish Acharya discussed the engineering requirements. The significance is the interface between automation and financial operations, rather than a claim that autonomous payments are risk-free. Permissions, transaction controls, exception handling and accountable human oversight remain important questions when evaluating such tools in practice.
Conventional payment modernization also continued. A January 2026 Omise announcement described a partnership with Visa to bring network tokens to Thai merchants and named customers already using the solution through Omise. In this context, tokenization replaces card details with controlled identifiers used in payment processing; it does not mean issuing a tradable cryptocurrency. The distinction is especially useful in a profile spanning both card payments and blockchain projects. Reported customer benefits remain attributed to the companies describing them, rather than treated as independently reproduced performance results.
Hasegawa’s CODAS role adds another strand to this work. The organization’s August 2026 launch-event release identifies him as chief project officer, corroborating Omise’s account of his appointment. CODAS’s stated objective is to make useful collaboration possible without organizations surrendering control of sensitive data. Omise described contributing payments knowledge to prospective cross-institution fraud-detection work. The documented contribution is leadership and participation in an emerging research-and-implementation effort; it is not proof of a fully deployed industry-wide fraud network.
Why Katharos.ai Follows Jun Hasegawa
Katharos.ai follows Hasegawa because his career connects experimental financial technology with the ordinary demands of merchants. A checkout flow, refund process or recurring payment has to work within an operating business, regardless of the architecture behind it. His record offers several ways to examine that problem: payment gateways, historical blockchain scaling, acquired processing infrastructure and AI-assisted operations. The most useful measure is the progression from a published idea to a clearly documented service.
His story also requires unusually careful attention to corporate boundaries. Omise, SYNQA and Opn appear at different points in the group’s history, while OMG Network’s ownership changed separately. CODAS is another organization with its own mandate and leadership. Following those distinctions produces a more accurate account of influence than grouping every associated product, token or partnership under one founder’s continuing personal control.
Areas to Follow
- Omise’s deployment and use of AI-assisted payment tools, including authorization, reliability and the handling of failed or disputed transactions. - How the group integrates merchant-facing services with processing infrastructure across its operating markets. - CODAS’s published research, implementation milestones and evidence of privacy-preserving collaboration in financial services. - The distinction between card-network tokenization, blockchain-based assets and any separately documented stablecoin initiatives. - New role or ownership announcements affecting the organizations associated with Hasegawa’s career.
Reporting Scope
This profile covers documented public leadership, company history and product development. Thailand is designated as a principal professional operating market, not as a claim about citizenship or current private residence; Japan and the other listed markets reflect the group’s documented footprint. OmiseGO founder history is not a current OMG management title. Funding announcements, partnerships and company performance claims are described only at the stage supported by their sources. No personal holdings, returns or investment recommendations are inferred.
Areas of Influence
Stablecoins & Payments is the principal category because of Hasegawa’s sustained work in merchant-payment services; that taxonomy does not imply that Omise itself issues a stablecoin. Exchanges & Infrastructure reflects his historical OmiseGO connection and the payment systems developed by the companies he has led. Investment & Founders captures entrepreneurship, fundraising and organizational expansion. His newer CODAS work is relevant where data governance and AI affect financial infrastructure.
